The difference between magnesium aluminum flat ruler and cast iron flat ruler

The difference between magnesium aluminum flat ruler and cast iron flat ruler Magnesium-aluminum flat feet and cast iron flat feet are the same: they are used for measuring levels;

Different points: The cast iron flat ruler has high precision and is generally used for debugging of machinery and equipment; the magnesium-aluminium flat ruler has relatively low precision and is generally used in various projects; the cast iron flat ruler includes bridge-shaped flat ruler, I-shaped flat ruler and rectangular shape. Flat feet, angle flat feet and special flat feet are used for machine tool guides. They are used for precision inspection of worktables, geometric accuracy measurement, measurement of precision parts, and scraping process processing. They are the benchmark for precision measurement. Parallel flat feet are flat feet foot-shaped gauge with a precisely planar shading to indicate that the table plate is examined flatness, elongated guide rail or the like, are also commonly used in the optical gap is examined in the straightness of the workpiece edges. Flat feet are generally made of high quality cast iron, and rectangular flat feet are also made of bearing steel or granite. Learn more about http://ZTPCXL.html

Ball Lens

Determine the effective focal length, the back focal length, and the effective numerical aperture of a ball lens based on its diameter, its refractive index, and the diameter of the collimated beam entering or exiting the ball lens. The effective numerical aperture of the application can only be calculated if the user knows the beam diameter. Knowing the numerical aperture is particularly useful when using ball lenses to couple light from a fiber to a laser or to another fiber.Ball lenses are commonly used to improve signal quality in fiber coupling applications, or for use in bar code scanning
applications or endoscopy.
Half-Ball lenses are ideal for applications such as fiber communication,endoscopy, microscopy, laser measurement systems and
optical pick-up devices,Such as including H-K9L(N-BK7), Sapphire, CaF2, BaF2, ZnSe or custom materials upon request.
Ball lens and half ball lens feature short back focal lengths to minimize the distance needed from the ball Lens to the optical
